Abstract

La présente invention concerne une buse de pulvérisation, une machine à laver à pulsateur, un système de pulvérisation pour celle-ci et un couvercle de tambour externe, permettant de résoudre le problème des machines à laver à pulsateur classiques peu efficaces en ce qui concerne la pulvérisation du linge à laver. Le système de pulvérisation de la machine à laver à pulsateur comprend principalement une pompe de circulation (8) et de multiples buses de pulvérisation (10) placées sur un couvercle de tambour externe (21). Une entrée d'eau de la pompe de circulation (8) est en communication avec une cavité interne d'un tambour externe (2), et une sortie d'eau de la pompe de circulation (8) est en communication avec les multiples buses de pulvérisation (10). Les buses de pulvérisation (10) comprennent un corps principal (101) et une structure formant barrière à l'eau (102) dotée d'un évidement incurvé sur le côté faisant face au corps principal (101). Pendant le fonctionnement, la pompe de circulation (8) pompe l'eau pour le lavage vers les multiples buses de pulvérisation (10), et l'eau est ensuite dispersée et déviée par l'évidement incurvé dans un tambour interne (3) de la machine à laver à pulsateur. Ainsi, la machine à laver à pulsateur pulvérise uniformément l'eau pour lavage dans le tambour interne (3) au moyen de la structure formant barrière à l'eau (102) dotée de l'évidement incurvé, ce qui améliore ainsi l'effet de pulvérisation de la machine à laver à pulsateur.
